Abstract: A pressure sensing pattern layer is formed on a substrate and comprises a plurality of pressure sensing electrodes. Each of the pressure sensing electrodes comprises a plurality of protruding portions. The protruding portions are formed from a transparent conductive line which is bent zigzag. Each of the pressure sensing electrodes is electrically connected to a Wheatstone bridge circuit through a first conductive line and a second conductive line. A resistance of each of the pressure sensing electrodes is an element of the Wheatstone bridge circuit. When any of the pressure sensing electrodes is touched, a variation of the resistance of the touched pressure sensing electrode is detected by the Wheatstone bridge circuit.

Abstract: A pressure sensing input equipment includes a substrate, a first surface and a second surface, an electrode layer, and a pressure sensing chip. The first surface and the second surface are disposed oppositely. The first surface includes a pressure sensing region and a non-pressure sensing region, in which the area of the non-pressure sensing region is complementary to the area of the pressure sensing region. The electrode layer includes a plurality of pressure sensing electrodes disposed in the pressure sensing region to detect pressure magnitude. The pressure sensing electrodes include a first end part and a second end part. The pressure sensing chip is electrically connected to the pressure sensing electrodes, and the pressure sensing chip determines pressure magnitude by detecting the resistance variation after the pressure sensing electrode was pressured. Such design can achieve double functions that detect touch position and pressure magnitude of the pressure sensing input equipment.
